To all whom it may concern:

,Be it known that I, MILTON F. WILLIAMS,

Fig. 1. 3 is a longitudinal sectional view of a modified form of cage-dumping mechanism, and Fig. I is a longitudinal sectional view on the line 44 of Fig. 3.

This invention relates to a newand useful improvement in dum ing-ca es for crushers and pulverizers, the o ject being to construct a cage in such manner that when the machine chokes it is possible to dump the contents thereof without raising the cover and removing the material from the top.

In the operationof my machine, especially where electric motors are employed as a driving medium, it sometimes happens that the fuse will blow out or other accidents happen during the time that the machine is in operation, causin the machine to stop and leaving the materia being operated upon in the mac 'ne.

Under these circumstances it is impossible to start the machine without first removing such material, it being necessary to get the machine up to full speed before introducing the material thereinto to be reduced.

My present invention therefore consists in making the grindingsurface or cage, with which the revolving heaters cooperate to re-- duce the material, Wholly or partly-movable, means for moving the same extending to the exterior of the machine, whereby in the event that themachine stops with a load or becomes choked it is possible for the o erator to dump the contents of the cagean free the machine. In the drawings, 1 indicates the side plates of the casing, and 2 is the cover.

. 3 indicates the breaker-plate, arranged at the front end of the machine and on which the material is first operated uponb the revolving hammers or beaters 4, w 'ch are pivotally mounted in the hammer-su ports 5, arranged on' a transversely-disposed s aft 6. 7 indicates the cage or grinding-surface,

which in this instance is made of two hinged parts, the free edges of which are contiguous. 6

otally connected by pins 19 tothe side plates 6 5 1 of the machine. ,A yoke-shape operatmglink 9 is fastened to the junction of these pairs of toggles by a pin 21, and said link 9 is connected by a pin 23 to a rack-bar 10, with which meshes a pinion 11, on whose shaft is a hand-wheel 12, located outside the casing.

By this construction when it is desired to dump either of the sections of the cage it is only necessary to operate the hand-wheel 12,

so as to move its-operating rack-bar 10 outwardly for actuating the link 9 to break the toggle, so as to permit the connected cage-sections to drop, as shown by dotted lines in Fig; 1.

When thecageis in normal position, as

shownin full lines in Fig. 1, the toggle-links form an efiicient and'rigid support therefor by reason of their pivotal centers being in a line.

- In Figs. 3 and a the cage-sections 7 are so mounted that their free ends are adjacent; but instead of connect' the toggle mechanism to the free ends of sand. ca e-sections I arrange pivoted levers 25 wit rollers 26 on their upper ends riding under the curved side bars of the cage-sections. 'Ihese levers 25 are pivoted at 27 to the side plates of the machine ,and have connected to them by pins 29 a yoke 9*, which in turn is connected to a rack-bar 10, whose rack meshes with a pin- 5 ion 11*, on Whose shaft is arranged a handwheel 12*". The operation of thls construction is obvious.

Having thus described the invention, what is claimed as new, and desired to be secured roe by Letters Patent, is I 1.- In a crusher or pulverizer, the comblnation of a sectional grinding-surface, the sections of which v are independently pivoted,

and an independent means connected to 10 each section and extending to the outside of the machine for actuating the said sections to se arate their free edges to dump the ma- .teria in the machine; substantially as demers or beaters, a sectional grinding-surface,

the sections of which are pivoted at different points so that the free edges of said sections are adjacent each other, and independently operable means connectedto said sections and extending to the outside of the casing whereby ,the free edges of said sections may be separated to dump the material in the machine substantially as described.

3. In a crusher or pulverizer, the combination of a casing, revolving hammers or beaters, a grinding-surface composed of independent sections mounted on fixed ivots, the free edges of said sections being a jacent each other, independently-operable mechanism arranged beneath the free edges of said sections for actuating said sections ,to separack-bar, and a hand-Wheel conjoined to said pinion, said hand-Wheel being located on the outside of the casing; substantially as described.

4. In a crusher or pulverizer, the combination of a casing, revolving hammers or beaters, a grinding-surface comprising a plurality of movable sections, a toggle mechanism connected to said sections, and means eX-' tending outside of the machine and connected to said toggle mechanism for operating the same and its connected sections to dump the materialin the machine; substantially as described.

In testimonywhereof I hereunto afiix my signature, in the presence of two witnesses, this 14th day of July, 1905.
